Today was the first day for students in the OC and we got things underway with a learning activity that illustrated the challenges of mining, engineering and environmental sustainability. The task involved students having to excavate mineral resources from the earth. The minerals and the earth were represented by choc chip and cream biscuits and students used mining equipment (toothpicks and spoons) to extract these riches. The challenge was to obtain maximum quantity and quality of minerals with minimum environmental impact. Students had a lot of fun examining and discussing this important issue. And thoroughly enjoyed eating the leftovers!
